SPECIFICATION formingpart' of Letters Patent No. 727,121, dated May 5,1903-. Application filed December ll, 1900; Serial No. 39,676. (Nomodel.)

To all whom it may concern: I Be it known that we, J OHN O. FREDERIC andALONZO D. FREDERICK, citizens of the United States, residing at SiouxFalls, in thecounty of Minnehaha and State of'South Da-' kota, haveinvented certain new and useful Improvements in Tubular Cream-Separatorsand we do hereby declare the following to be a full, clear, and exactdescription of the in vention, such as will enable others skilled in theart to which it appertains to make and described, and particularlystated in the claims.

The principal object of the invention is to obtain a rapid and thoroughseparation of the cream from themilk, and this and other objects areattained by means of the apparatus illustrated in the drawings, inwhich- Figure 1 is a side elevation of our improved apparatus, partlybroken away around the water-draW-ofi faucet to show the waterchamber;Fig. 2, a perspective view of the can proper and the water-tubesseparated, and Fig. 3 a plan view of the top.

In the several views the numeral 1;indicates the milk-reservoir,provided with a drawoif faucet 2 and with upper and lower transparentpanels 3 3, the latter being for the in-' spection of the milk duringthe process of separation and drawing off.

A water-chamber 4 is formed around the milk-reservoir by a jacket orcasing 10, provided with a suitable bottom and base, as shown, and witha suitable draw-off faucet9, communicatingwiththewater-chamber; Themilk-reservoir is suspended from. thetop of the jacket or casing bymeans of brackets ll, and the side edges of the jacket-or casing areturned in and secured to the wall of the milk reservoir on each side ofthe transparent panels, as shown at 12 12.

The milk-reservoir is provided with a conically-shaped cover 5, and inthe apex of said cover is a wire-gauze a, which adapts the cover whenreversed to be used as a strainer for straining the milk into thereservoir. Attached to the cover are two depending U- shaped water-tubes6 6, one end of each being secured flush with the upper surface of thecover, as shown, the other end of each projecting slightly above thecover and having attache dthereto a funnel 8, into which said ends open.The water-tubes extend down into the milk-reservoir to within a shortdistance of its bottom, and located in one of the arms of one of saidtubes is a pump 7, the bottom-of which is provided with a suitablelvalve b, held normally closed by a spring I).

The lower end of the pump tube passes through the bottom of thewater-tube and is secured water-tight thereto. The pump-rod is providedwith a suitable handle, as shown,

bym eans of which the pump is operated.

In operating our separator the cover is reiversed and the milk passedthrough the strainer until the required amount is put into themilk-reservoir, after which the strainer is cleaned and the coverreplaced in normal position.

Cold water is now applied to the funnel 8 and passing through theWatertubes overflows and runs down the upper surface of the cover intothe water-chamber surrounding the milk reservoir, passing out throughthewater-draw-oif faucet when run.- ning water is being used, thuscausing acontinuouscnrrent to pass through and around the milk. A smallquantity of watersayfrom half a pint to a pint-is poured into the pumpand the pump operated for about two minutes and then at intervals forabout ten minutes. Practically complete separation will take place inabout forty minutes. After the cream has become separatedfrom the milkthe latter is drawn off through the fan- Get 2, the transparent panelspermitting inspection during the operation. After the milk has beendrawn off the cream can be removed through the samefaucet.

It'will be obvious that the colder the water the more rapid theseparation and that the thorough circulation of the water through andaround the milk and the infusion of air in the fatty substances thereofcauses a rapid and substantially complete separation of the cream fromthe milk. It will be understood that the strainer to also serves as avent for the escape of the odors arising from the animal heat in themilk. 7

Having thus fully described our invention, what We claim as new, anddesire to secure by Letters Patent, is

1. In a cream-separator, the combination with a milk-reservoir and awater-chamber surrounding the same, of a top or cover provided with oneor more bent water-tubes, said tubes having a supply end and an overfiowend, substantially asspecified.

2. In a cream-separator, the combination with a milk-reservoir and awater-chamber surrounding the same, of a top or cover provided with oneor more bent water-tubes, said tubes having a supply end and an overflowend, and a pump located in one of the watertubes and connecting with themilk-reservoir, as and for the purpose specified.

3. In a cream-separator, the combination with a milk-reservoir and awater-chamber surrounding the same, of a top or cover provided with anair-vent and having attached thereto one or more bent water-tubes, saidtubes having a supply end and an overflow end, substantially asspecified.

4. In a cream-separator, the combination with a milk-reservoir and awater-chamber surrounding the same, of a top or cover provided with anair-vent and having attached thereto one or more U-shaped water-tubes,said tubes having supply ends and overflow ends, and a pump located inone of said tubes and connecting with the milk-reservoir, as and for thepurpose specified.

5. In a cream-separator, a vessel for retaining the milk, a removablecover fitted to the top of the vessel, a plurality of open-top tubesfixed in apertures in the cover and connected at their lower ends byhorizontal sections, as and for the purpose described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
